Dustin Dale Allen, 20, has been charged with first-degree murder in the Sept. 13 slaying of Mary Ellyn Benavidez, 57. According to court documents, Allen told police that he was angry at Jason Benavidez, Mary Benavidez's son, with whom he was previously friends.

Allen said he went to the Benavidez home in the 1200 block of Stubbeman Avenue in Norman with a firearm, according to court documents. When Allen arrived at the home he kicked in the front door and went to Jason Benavidez's bedroom, court documents say.

Allen told police he could not find Jason Benavidez, so he confronted Mary Benavidez, according to court documents. As Benavidez was backing away from Allen, he fired one shot that hit her in the chest, court documents say.

He then fled the scene in a Dodge Caliber, according to court documents. Shortly after the Oklahoma City Police Department was responding to an attempted robbery and seeking a light-colored Dodge Caliber they believe was connected, court documents say.

Officers then located a vehicle matching the description of the one that fled Benavidez's Norman home, according to court documents. Allen admitted to police that the vehicle was his, court documents say. He was able to escape police, but was later caught, according to court documents.
